I just bought an 84 blazer and it has 6 inches of lift on it. Is there a way for me to figure out what particular lift was put on it? i.e. superlift or skyjacker or whatever? Also, I have some really basic questions because I'm new to this. Can I leave the hubs locked during the winter so that if I come across a need for 4wd I can just shift on the fly? Or does leaving them locked damage something? Do i need to do the reverse for 10 ft thing when going from 4hi back to 2wd or is that just coming out of 4lo? thanks everyone for your patience with my rookie questions!
